Fisher information and physics

Joseph Wilson (OSU)

Abstract

1. Use of Shannon's information measure (entropy) in a couple of real problems. One example is drawn from operations research and one drawn from image reconstruction.
2. Brief introduction to Fisher's Information measure. A little bit of history. Some basic properties and a simple example.
3. Show how Fisher Information measure arises in the Lagrangians for the Schrodinger, Klein-Gordon, Pauli and Dirac equations.
4. Prove a couple of interesting inequalities.
